Introduction to Linux - A Hands on Guide

This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I normally use Eclipse 3.2 for learning Java, and i've configured it to run Jre 1.5. Eclipse is really awesome great but its loading times are getting on my nerves, especially since it makes me create packages and such for simple beginner programs.

I wish to use either Emacs or Vim or KDevelop with console support but I don't know how to make Jre 1.5 the default, when I use javac <file>, console uses the eclipse-jre 1.4 compiler. I know how to compile and run with gcj but that too is a 1.4 compiler.

I whish to run a 1.5 based jre as my study material requires jre 1.5, i don't mind if it's GNU or not, just a solution that can be called up quickly.

Just would like to point out that there are other IDE's available. One that is very famous in IT-schools and Universities is BlueJ. It works great and won't get on your way of doing things, plus it does not take so long to start up.

However, I've to say that it is better to learn Java concepts from the very start. Sooner or later you will have to move to another IDE as Eclipse. Real-time compiling and syntax check will come in hand when your programs get bigger. Well, IMHO indeed ^_^.
